Renaud Laplanche, Lending Club

Renaud Laplanche changed his daily routine to save not just money, but time. The co-founder and chief executive officer of Lending Club, an online service that connects individual lenders with borrowers, figures he'll save more than $1,000 per year simply by buying a better coffee machine for his home.

Rather than stop at Starbucks each morning for a tall, white mocha, Laplanche has started to brew better coffee at home. It tastes as good, he says, "and I get to the office 15 minutes earlier. That feels great."
